I have 2 arrays. The one contains the name of all the keys of the 2nd array like the following.
const additionalFields = ['phoneNumbers', 'ageOrDobs', 'genders', 'usernames', 'employments', 'educations', 'websites', 'affiliatedOrganizations'];
const fields= [{
affiliatedOrganizations: []
ageOrDobs: []
educations: []
emails: [{…}]
employments: []
genders: []
locations: [{…}]
names: [{…}]
phoneNumbers: []
usernames: []
websites: []
}]
Now, I want to loop through the additionalFields based on the value I receive I want to check if the key of fields have length greater than 0. For example.. fields.phonenNumbers.length > 0 but the key phoneNumbers will be coming from loop
additionalFields.map((opts) => {
if(fields.opts.length > 0){ //this one doesn't work...
//do something
}
}
I am using typescript and fields have a interface related to the values in it as shown above. Please help me with this... thank you!!
Just use the Bracket notation:
additionalFields.map((opts) => {
if(fields[opts].length > 0){ //this one doesn't work...
//do something
}
}
Example:
const person = {
firstname: 'John',
lastname: 'Doe'
}
const key = "firstname"
console.log(person[key]) // John
